This thesis intends to reconsider the concept of purgatory as it was established and used by the historians of the late twentieth century; show that this redefined...

This PhD report deals with modeling formalisms for multi-physical systems in the design V- cycle. This work was carried out within the French ANR-MoCoSyMec project,...

This thesis investigates the mechanical behavior of all-metal sandwich panels with anticlastic core structures. Anticlastic core structures provide a cost-effective...

Effects of atmospheric turbulence, on long distance endo-atmospheric propagation (over a few miles), can be seriously detrimental to free-space optical communications...

A periodic, ordered and noncohesive structure of monodisperse spherical beads forms a granular phononic crystal. This work is devoted to the propagation of an acoustic...

Rédaction débutée fin juillet 2010.

The sonication of a tumor, where liposomes have been accumulated, allows potentially to release encapsulated drug and to promote its absorption in cells. Ultrasonic...

Food business operators are responsible for the quality of the products they sell. A way to assess the safety of food is to determine the contamination distribution....

Rock instabilities are one of the most common natural risks encountered in high alpine relief and, despite this fact, they still remain largely uncharted in Earth...

In this thesis, we build a large number of global solutions for many supercritical Schrödinger equations. The method is to make the random initial data, using the same...

The majority of studies made on transcription factors dynamics on living cells agree with a fast dynamics process. However, there is some exceptions such as the...

Today, enterprises face rapidly changing market conditions, new competitive pressures, new regulatory fiats that demand compliance, and new competitive threats. To...

Phase Change Memories are suitable for the next generation of non volatiles memories due to high programmation speed and endurance. However, two major improvements...

This thesis proposes to update and extend the main contributions of the founders of the concept of collective memory: Halbwachs (1925/1992, 1941/2008, 1950/1997) and...

Given a set S of data points on a surface F whose equation is z = f(x,y), we would like to triangulate the convex hull of the projection of F on the xy-plane. This...

For a few years, meshes have been conquering a predominant status amongst the different types of computer data structure for geometric objects. More precisely, the...

The Pan-African belt ot the Hoggar and the Adrar des Iforas results from the collision between the West-African Craton and the Pan-African mobile belt. In Mali, the...

The cryptographic blocks used in the integrated circuits implement algorithms proved robust against cryptanalysis. However, malicious manipulation against the circuit...

The work presented in this PhD thesis contibutes to a new method for a modified particle swarm optimization algorith (MPSO) combined with a simulating annealing...

The dictates of miniaturization and increased performance followed by microelectronics manufacturers faces currently physical, technological and economic limitations....
